1 <html><head><title>toybox news</title> 2 <!--#include file="header.html" --> 3 4 <p>Toybox combines common Linux command line utilities together 5 into a single BSD-licensed executable that's simple, small, fast, 6 reasonably standards-compliant, and powerful enough to turn Android into 7 a development environment. See the links on the left for details.</p> 8 9 <h2>News</h2> 10 11 <hr><b>April 5, 2015</b> 12 <p>Since <a href=https://android.googlesource.com/platform/external/toybox/>android</a> and 13 <a href=https://git.tizen.org/cgit/platform/upstream/toybox.git>tizen</a> 14 and <a href=https://github.com/kraj/meta-musl/tree/master/recipes-core/toybox>openembedded</a> 15 and <a href=https://packages.gentoo.org/package/sys-apps/toybox>gentoo</a> 16 and so on have all been using Georgi Chorbadzhiyski's git mirror rather 17 than the mercurial repository, I bit the bullet and switched the project's repo 18 <a href=https://github.com/landley/toybox>to git</a>. Georgi's 19 <a href=https://github.com/gfto/toybox>mirror</a> is now pulling from that.</p> 20 21 <hr><b>February 25, 2015</b> 22 <blockquote><p>"A common mistake that people make when trying to design 23 something completely foolproof is to underestimate the ingenuity of 24 complete fools."</p><p>- The Hitchhiker's Guide to the Galaxy.</p></blockquote> 25 26 <p><a href=downloads/toybox-0.5.2.tar.gz>Toybox 0.5.2</a> 27 (<a href=/hg/toybox/shortlog/1702>commit 1702</a>) is out.</p> 28 29 <p>New promoted commands: sed (finally fixed enough it builds Linux From 30 Scratch), printf (cleaned up and promoted), shred and 31 base64 (the Tizen guys wanted them), getenforce, setenforce, and chcon (android), 32 mix (promoted with fixes from Isaac Dunham), nsenter (from 33 Andy Lutomirski, merged into unshare).</p> 34 35 <p>Elliott Hughes submited a bunch of patches to support Android (to 36 both toybox and Bionic libc, which he maintains). On toybox's end this 37 involved a lot of fixups to portability.[ch] and fixes to over a dozen 38 commands, plus several new ones. Other portability fixes included working 39 with buildroot's uclibc fork and building for nommu targets.</p> 40 41 <p>The new "make change" target builds each toybox command as a standalone 42 binary. Rather a lot of commands that didn't build by themselves (mv depending 43 on cp and so on) were hit with a large rock until they built standalone. 44 This involved rewriting bits of option parsing, more elaborate dependency 45 generation, making each command have its own config 46 symbol and main() function (even when it's just a wrapper calling another 47 command's main()), and so on. Also, some commands can't be built standalone 48 at a conceptual level: "help" describes other enabled commands and "sh" 49 has a number of bulitin commands (cd, exit, set) that require the 50 multiplexer infrastructure, so "make change" filters them out.</p> 51 52 <p>The mailing list's web archive is still screwed up. Dreamhost has 53 been trying to fix it since approximately September. There are 54 <a href=http://www.mail-archive.com/toybox@lists.landley.net/>two</a> 55 <a href=http://news.gmane.org/gmane.linux.toybox>other</a> less broken 56 archives, but neither has quite the same UI as mailman.</p> 57 58 <h3>Bugfixes and tweaks</h3> 59 60 <p>Cynt Rynt sent in tests for ifconfig, 61 Robert Thompson taught factor to accept whitespace separated arguments, 62 Hyejin Kim pointed out that some of mktemp's longopts were attached to 63 the wrong short options, 64 Luis Felipe Strano Moraes fixed a wrong free() call in bootchartd in pending. 65 Patches from Ashwini Sharma to make "df /dev/node" work, prevent du from 66 looping endlessly following symlinks, and to make expr.c 67 (in pending) understand == and regex matches. (Speaking of expr, it gets 68 priority groupings wrong but the bug was actually in the posix spec's 69 HTML conversion. They fixed the posix spec upstream for us. Still need 70 to fix the expr code, but it's in pending for a reason...)</p> 71 72 <p>Some commands grew new option flags, such as cp --remove-destination 73 and touch -h.</p> 74 75 <p>The parallel build has better error reporting now. When toybox needs to 76 re-exec itself to regain suid root permissions and hasn't got the suid bit, 77 it now gives the right error message ("not root" instead of "no such command"). 78 79 <p>Added a test to "mount" to not mount the same device/directory combination 80 over itself (the OS catches this for block devices, but not for tmpfs). 81 Make blkid distinguish ext3 from ext4. Added catv back into cat (because 82 the Android guys wanted it, and they have historical usage on their side, 83 so...). Handle nanoseconds in touch.</p> 84 85 <p>Fixed a segfault when CP_MORE was disabled (the resulting option flag list 86 no longer defined -d but still had it in option groups at the end). 87 Workaround for glibc redefining dirname() and basename() to random non-posix 88 semantics because gnu. (They could have created dirname_r() but didn't want 89 to.)</p> 90 91 <p>Fix an ifconfig test that was preventing assigning an ipv4 address to 92 interface aliases. Several cleanup passes on hwclock but not quite 93 promoted out of pending yet.<p> 94 95 <p>Fixed a wrong error message in rm (if you had a chmod 000 directory and 96 did rm -r on it without -f, after the prompt it would complain it was a 97 directory, which was not the problem).</p> 98 99 <p>The gzip compression code now does "store only" output to stdout, for 100 what that's worth.</p> 101 102 <p>Cleanup mountpoint and expand, and remove them from toys/pending/README 103 (a list of commands that predate the toys/pending directory but needed 104 another pass).</p> 105 106 <h3>Library and infrastructure:</h3> 107 108 <p>Reworked the option parsing infrastructure so more commands build 109 standalone (via scripts/single.sh or "make change"). The option flag bit 110 values are no longer packed, it leaves spaces where currently disabled 111 flags go, and you can #define FORCE_FLAGS so disabled flags aren't zeroed. 112 This allows multiple commands to more easily share infrastructure, even if 113 your current flag context is for a disabled command (switched off in config), 114 you can force them to stay on and as long as the flags read the same right 115 to left they'll have the same values.</p> 116 117 <p>We've started removing use of strncpy() because it's a hugely broken 118 standard C function: the length is the maximum length to _append_, not 119 the size of the destination buffer. It memsets the remaining space it didn't 120 copy ala "memset(dest+strlen(dest), 0, len);" so 121 if you think len is the size of dest you're guaranteed to stomp memory off the 122 end). And if it runs out of space it won't null terminate because reasons. 123 (Meanwhile sprintf("%*s", len, str) is counting wide characters in your current 124 locale, so if you set a locale other than "C" it will also go past your 125 allocated buffer size. Whoever is maintining the C library standards is really 126 bad at strings.) 127 Instead we have xstrncat() which will error_exit() if src+dest+1 doesn't 128 fit in the buffer. (Because randomly truncating input data isn't necessarily 129 an improvement.) And there's always xmprintf().</p> 130 131 <p>Similarly, strtol() doesn't return an error indicator on overflow, 132 you have to clear and then check errno. So new xstrtol() that cares 133 about overflow.</p> 134 135 <p>The bionic and musl guys agree faccessat(AT_SYMLINK_NOFOLLOW) is not 136 supported, so stop using it.</p> 137 138 <p>Fixed toy_exec() to detect when argc is in optargs, so we don't 139 need a separate xexec_optargs().</p> 140 141 <hr><b>February 18, 2015</b> 142 <p>Dreamhost continues to be unable to make mailing list archives work, so 143 here's <a href=http://www.mail-archive.com/toybox@lists.landley.net/>another 144 list archive</a> with a less awkward interface than gmane.</p> 145 146 <p>(Neither gives you the convenient historical monthly views of mailman, 147 but I still have hopes dreamhost will someday figure out what they're doing 148 wrong. They've only been trying since October. Last month they did a 149 <a href=http://www.dreamhoststatus.com/2015/01/14/discussion-list-hardware-maintenance/>hardware upgrade to fix a software problem</a>, and the stale 150 data loads much faster now, so that's something.)</p> 151 152 <p>Update (Feb 19): the archive started updating again, by discarding 153 all the pending data. So there are now _two_ giant holes in Dreamhost's 154 web archive, from Dec 15-Jan 3, and then another hole from Jan 16-Feb 18. 155 The relevant messages are in both of the other archives. Here's hoping 156 the chronic archive constipation problem won't happen a sixth time.</p> 157 158 <hr><b>December 30, 2014</b> 159 <p>Due to Dreamhost's <a href=http://landley.net/dreamhost.txt>ongoing</a> 160 <a href=http://landley.net/dreamhost2.txt>inability</a> to make mailman 161 work reliably, I've added a link to a backup web archive at 162 <a href=http://news.gmane.org/gmane.linux.toybox>gmane</a> to the nav bar 163 on the left.</p> 164 165 <p>You still subscribe to the list through 166 <a href=http://lists.landley.net/listinfo.cgi/toybox-landley.net>the first link</a>.</p> 167 168 <p>Update (January 27, 2015): they're <a href=https://twitter.com/landley/status/558428839462703104>still working on it</a>.</p> 169 170 <hr><b>November 19, 2014</b> 171 172 <blockquote><p>"This time it was right, it would work, and no one would have to get nailed to anything." - The Hitchhiker's Guide to the Galaxy.</p></blockquote> 173 174 <p><a href=downloads/toybox-0.5.1.tar.bz2>Toybox 0.5.1</a> 175 (<a href=/hg/toybox/shortlog/1566>commit 1566</a>) is out.</p> 176 177 <p>It's an interim release, mostly bugfixes. There are several new commands, 178 but they're all in pending.</p> 179 180 <h3>Development</h3> 181 182 <p>Finally implemented sed, which is still in pending because although 183 it's feature complete according to posix, and even passes the parts of 184 Busybox's sed test suite that aren't explicitly testing for gnu bugs we 185 don't want to copy, it's not yet good enough to build Linux From Scratch. 186 (The ./configure stages use very long sed scripts. 20 commits worth of 187 implementation and debugging, just under 1000 lines of code, and there's 188 still more to do. We're definitely up to some of the "fiddly" commands now. 189 Did you know "echo hello | sed p - -" segfaults gnu sed in Ubuntu 12.04? 190 Yeah...)</p> 191 192 <p>Talked with the Tizen developers to follow up on their desire to 193 make toybox a part of the base Tizen system, and got a list of commands 194 to add to the roadmap. The tizen todo list is:</p> 195 196 <blockquote><p> 197 wget, sha256*, gzip, gunzip, bunzip2, rsync, zdiff*, 198 less, ar, arch, base64, csplit, dir, fmt, join, 199 nproc, shred, shuf, stdbuf, stty, test, tr, unexpand, 200 users, vdir, diff3, sdiff, dosfsck (fsck.vfat), awk, fdisk 201 </p></blockquote> 202 203 <p>(Most of which was already on the todo list, but it helps prioritize.)</p> 204 205 <p>Fixed md5sum and sha1sum on big endian systems (reported by James McMechan). 206 Andy Lutomirski fixed unshare's help text and option parsing, 207 and submitted nsenter (a tool to use setns(2)) to pending. 208 Isaac Dunham implemented acpi -ctV options, and spotted the bug that ls -d 209 was inappropraitely following command line symlinks without -H or -L (it 210 should act like ls -l does), and ls -F handles symlinks wrong too. 211 Lukasz Szpakowski sent in two bugfixes to tail.c. Cynt Rynt spotted an 212 unnecessary assignment in lib/password.c.</p> 213 214 <p>Ashwini Sharma's team was as busy as usual, submitting tr, crontab, and 215 ipcrm, and hwclock to pending, more features to the pending ip.c, and a 216 pile of bugfixes (to chgrp, killall, ifconfig, insmod, 217 losetup, comm, cp, id, xwrap, netcat, modprobe, nohup...) mostly found by 218 static analysis. (These fixes are mostly to seldom-used codepaths like the 219 TOYBOX_FREE config option, but test coverage is always appreciated.) Ashwini 220 also suggested upgrading ln -f to leave the original target alone if link 221 creation fails, and reported that mv -f and -i weren't implemented (now fixed).</p> 222 223 <p>New config option: TOYBOX_NORECURSE prevents xexec() from making internal 224 function calls (for nommu systems with a finite stack).</p> 225 226 <p>The "toybox" multiplexer command no longer adds a trailing space to each 227 line of command names, so things like "./toybox | tr ' \n' '|'" to create 228 a grep pattern snippet are easier to do. (Why you'd want to is your business, 229 but the output is tidier now.)</p> 230 231 <h3>Infrastructure</h3> 232 233 <p>Isaac Dunham added Android support to portability.h, including compile 234 probes for functions missing from bionic-libc, and annotated the commands that 235 use those functions. We haven't really tested building against bionic, 236 but in theory it's possible now.</p> 237 238 <p>Running the test suite now color codes the PASS/SKIP/FAIL notifications 239 if output is to a tty. (And in case you missed it last time, VERBOSE=fail 240 to stop at the first failure is really useful.)</p> 241 242 <p>In loopfiles_rw() use O_CLOEXEC instead of O_RDONLY to request the loop 243 function close filehandles for us. (Otherwise the callback function must 244 close each supplied filehandle itself.)</p> 245 246 <p>The printf-style escape parsing ("\n" and friends) got factored out into 247 a new unescape() function.</p> 248 249 <hr><b>October 2, 2014</b> 250 <blockquote><p>"There is an art, it says, or rather, a knack to flying. 251 The knack lies in learning how to throw yourself at the ground and miss... 252 Clearly, it is this second part, the missing, which presents the 253 difficulties." - The Hitchhiker's Guide to the Galaxy.<p></blockquote> 254 255 <p><a href=downloads/toybox-0.5.0.tar.bz2>Toybox 0.5.0</a> 256 (<a href=/hg/toybox/shortlog/1512>commit 1512</a>) is out.</p> 257 258 <h3>New commands</h3> 259 260 <p>The new commands are find, install, factor, and mount. Promoted commands 261 (cleaned up and moved out of "pending") are lspci, inotifyd, and blockdev.</p> 262 263 <p>cp now implements -HL and -F to force delete of pending files, cpio now 264 ignores -m and implements -p, ls -C now has utf8 support (using wcwidth 265 instead of strlen), and umount got a number of upgrades involving 266 looking things up in /proc/mounts. Other minor cleanups happend to 267 cut, touch, free, and id.</p> 268 269 <p>In pending: Bradley Controy submitted mix (adjusts OSS sound volume). Ashwini 270 Sharma submitted diff, userdel, blockdev, ipcs, and crond, upgraded 271 fdisk, fsck, and ftpget, and ran a static analyzer on a lot of other code. 272 Partial cleanup was done to useradd, userdel, groupadd, and groupdel.</p> 273 274 <h3>Build infrastructure</h3> 275 276 <p><b>Parallel builds</b></p> 277 278 <p>The build now takes advantage of SMP, autodetecting the number of 279 processors. (Export the environment variable CPUS to pick a specific number.) 280 Other build changes: split out $LDOPTIMIZE because old compilers complain 281 about linker options passed with -c, and the entire "generated" directory now 282 gets deleted by clean (the README that was in there got merged into code.html).</p> 283 284 <p><b>Standalone builds</b></p> 285 286 <p>The standalone build infrastructure (scripts/single.sh) got upgraded to 287 build more commands as standalone executables. In make.sh the source file 288 selection uses a regex to find the source files with the NEWTOY/OLDTOY macro 289 for the command. It enables each command's 290 sub-options (so CP has CP_MORE), enables I18N and FLOAT support to build 291 full-featured commands, and includes --help text (at least when 292 the command doesn't use another command's help). The OLDTOY() macro 293 now produces (redundant) function prototypes so you can build an OLDTOY 294 without the NEWTOY</p> 295 296 <p>It doesn't quite have complete coverage yet, the defconfig entries that 297 aren't building standalone yet are:</p> 298 299 <blockquote><p>chown, egrep, fgrep, fstype, halt, mv, nc, poweroff, unix2dos, 300 whoami</p></blockquote> 301 302 <p>The main reason for standalone build failures is NEWTOY() or OLDTOY() 303 entries that don't have their own config symbol. Another problem is entries 304 that depend on another entry in kconfig, usually because common infrastructure 305 is using one command's flags (which the other commands copy): if that command 306 is disabled, the FLAG macros become 0 so dead code elimination can remove the 307 code. It's <a href=http://landley.net/hg/toybox/rev/1503>possible 308 to untangle</a> this, but a bit awkward. (It boils down to conflicting 309 design goals in the two contexts.)</p> 310 311 <p>Standalone builds are used by the test suite when testing individual 312 commands. 313 314 <p><b>Snapshot builds</b></p> 315 316 <p>A new addition to the "generated" directory is generated/build.sh 317 containing a single compiler command line to build toybox in its current 318 configuration. Combined with the generated/*.{h,sh} files from an 319 exisiting build, this may let you build on a new system that hasn't quite 320 got enough OS bits working to run a full configureand make.</p> 321 322 <h3>Internals</h3> 323 324 <p>Library code: xcreate/xopen now O_CLOEXEC by default to avoid leaking 325 filehandles to child processes. DIRTREE_COMEAGAIN's second callback is now 326 done with the directory filehandle still open (new dir->again variable added 327 to distinguish first from second callback, and requesting DIRTREE_RECURSE now 328 requires passing in the specific macro value, not just a true/false). 329 Use daemon() out of libc instead of hand-rolled daemonize() in various 330 pending commands. string_to_mode() now passes through type bits so you can 331 use it to more easily modify a file's existing mode. 332 Split xpopen() into xpopen_both(), xopen(), and xrun() depending on whether 333 we want to redirect both, one, or neither of stdin/stdout.</p> 334 335 <p>Bugfixes: Better error message when TOYBOX_SUID option can't drop priviliges 336 (which happens when you suid something _other_ than root). 337 The old pending version of nbd_client.c wasn't deleted when the 338 command was promoted (and the build would break if both were enabled), 339 toy_exec() sometimes needs to re-exec from $PATH rather than recurse 340 internally (to gain dropped root permissions or limit stack depth), 341 always call setlocale() when I18N is enabled to switch it back _off_ when 342 we run commands that expect sscanf("%n") to return bytes, 343 dirtree() had a memory leak in an error path, patch.c had some bugs in 344 error paths (didn't report problem clearly). Ashwini Sharma spotted an 345 option parsing bug where [-abc] would forget _all_ command line arguments 346 saved in the GLOBALS() block (not just the ones for options being switched 347 off), plus various minor fixes to nbd_client and cpio. 348 Lukasz Szpakowski fixed rm -f on a broken symlink (failed), and killall 349 with no arguments (segfaulted).</p> 350 351 <p><b>Portability</b></p> 352 353 <p>A somewhat fiddly fix to rm -rf (which needs to chmod directories to u+rwx 354 to descend into them) which hit a musl bug in faccessat() which the musl 355 maintainer refuses to fix. (He literally wants the man page changed 356 instead, despite other libcs working.) Added an #ifdef __MUSL__ section 357 to portability.h with a workaround, you may need CFLAGS=-D__MUSL__ in your 358 build if your musl build's features.h doesn't #define that. (I may do 359 a different workaround in future, but sometimes you've just got to make 360 it work so you can ship. Also, toybox grep with multiple patterns 361 requires <a href=http://landley.net/hg/aboriginal/rev/1692>a patch 362 to musl's regex engine</a>, which applies to 1.1.4 but not to the current 363 musl source control.)</p> 364 365 <p>More portability.h fixes for uClibc too. (I don't expect that to ever have 366 another release, so locally patching around posix-2008 violations is silly).</p> 367 368 <p><b>Change to username filtering</b></p> 369 370 <p>Posix recommends the username creation logic filter usernames to a small 371 allowed set of characters (which even Red Hat breaks by explicitly allowing 372 "$" at the end), but this prevents UTF-8 usernames. Posix' stated logic 373 is to allow filesystems to create the user's home directory, but Linux 374 filesystems can accept any character but NUL and "/". The only characters 375 we actually _need_ to filter out are ":" (field separator in passwd), 376 newline (line separator in passwd), and "/" (directory separator in 377 filesystem).</p> 378 379 <h3>Documentation</h3> 380 381 <p>Web pages updated: cleanup.html documents more cleanup, code.html 382 documents more code, and about.html now capitalizes "toybox" consistently 383 (it's just a word, capitalize at start of sentence).</p> 384 385 <p>The pending/README file now lists commands that needed review/cleanup 386 before the pending directory was added.</p> 387 388 <h3>Test Suite</h3> 389 390 <p>Moved out of scripts/test into top level "tests" directory, and the 391 testing.sh script is now in scripts rather than mixed into the *.test files.</p> 392 393 <p>Johan Bergstrm requested VERBOSE=fail to make tests (telling it to 394 stop at the first failure), and spotted a build bug where using gnu 395 sort on the host broke in non-C locales.</p> 396 397 <p>Divya Kothari submitted tests for chmod, link, tar, bzcat, xzcat, zcat, 398 and hostname. (And more, but that's all that's merged so far.)</p> 399 400 <hr><b>July 7, 2014</b> 401 <blockquote><p>"This planet has - or rather had - a problem, which was this: 402 most of the people living on it were unhappy for pretty much of the time.

Expand the 433 "coding style" section in the docs and move it to design.html. (Not a show 434 stopper for incoming 435 contributions, just an explanation of some of the things I'll do to them 436 during cleanup.) The help text for the "toybox" command now includes 437 the shell script snippet to install symlinks to the toybox binary.</p> 438 439 <p>The <a href=cleanup.html>cleanup page</a> now has descriptions for the 440 full ifconfig cleanup series, among others.</p> 441 442 <p>The new toys/examples directory contains hello.c and skeleton.c.

Ashwini Sharma reported 451 bugs where readfile() was incorrectly freeing its buffer, and where toy_init() 452 was zeroing the wrong data because the field it was using to measure (rebound) 453 had moved (when I moved it back I added a comment why the field needs to be 454 there), fixed a segfault in the dhcp client, and made a 0 length read at 455 the start of password entry count as EOF. Make the "we are not root" test 456 in the init code show the help text. Posix implies that fflush() can return 457 success even when the stream's error bit is set, so call both fflush() and 458 ferror() from xprintf().</p> 459 460 <p>Isaac Dunham pointed out that bloatcheck couldn't deal with diff 461 implementations that only implement "unified diff" format, and that some 462 diff implementations can't handle nonseekable input (I.E. reading from 463 a pipe). Bugfix so "help -a" works again. Option parsing on nohup now stops 464 at first nonoption argument. Fix segfault in "which" if PATH wasn't set, 465 which was actually a bug in lib function find_in_path(). Made rm -rf of 466 chmod 000 directories actually remove them.</p> 467 468 <p>The build now passes the same $CFLAGS to the library probe as the final 469 build, because arch linux is so broken it provides different sets of 470 libraries for static and dynamic linking.</p> 471 472 <p>It turns out sprintf("%.123s", str) is counting characters, not bytes, 473 so globally enabling locale support opens stack smashing vulnerabilities. 474 So there's a new TOYFLAGS_LOCALE you set in toyflags when you want the 475 setup code to setlocale().</p> 476 477 <p><b>Upgrades:</b></p> 478 479 <p>Isaac Dunham extended cpio to archive unreadable empty files, and I taught it 480 to set uid/gid and timestamp when extracting archives. Isaac also 481 added tests for cpio, link, and du, added lspci -i, made the pci database 482 parsing skip # comment lines, merged logname and whoami into id.</p> 483 484 <p>Daniel Verkamp sped up md5sum about 30% with some loop unrolling, making 485 it actually smaller in the process. I added -b flags to md5sum and sha1sum 486 for "brief" output that's just the hash with no filename. (I'm aware other 487 implementations use that for MSDOS "binary" mode, and don't care.)</p> 488 489 <p>When building standalone commands (scripts/singleconfig.sh commandname), 490 the build now switches on all the sub-options of the command so we get 491 a standalone version with all the bells and whistles enabled.</p> 492 493 <p>Add -ds flags to date and document +FORMAT escapes. Add the shell NOP 494 command ":" as an alias for true (for toysh).</p> 495 496 <p>Add uClibc probe for iconv() and fallocate. (The fact it didn't always 497 build against uClibc is why fallocate wasn't enabled in defconfig before.)</p> 498 499 <p>The umount command now does an losetup -d on the device by default, so 500 we don't leak loopback devices. Bugfix to losetup so "losetup /dev/loop0 501 filename" actually works again.</p> 502 503 <p>Divya Kothari sent in test suite entries for ls, ln, rm, mv, printf, dd, 504 and renice. Then a second round for lsattr/chattr, mount, chmod, pgrep/pkill, 505 groupadd, groupdel, and useradd. Several of these uncovered bugs, still 506 working to fix them.</p> 507 508 <p>There are now free() functions for the predefined llist types and a 509 dlist_terminate() function to break doubly linked lists. The new 510 generic_signal() handler either sets "toys.signal" or writes a byte 511 to toys.signalfd with the signal number if signalfd isn't -1 (which it's 512 initialized to in toy_init).</p> 513 514 <p>The option parsing logic can now detect when a double fits in a long and 515 use the more precise type for floating point arguments (the FLOAT macro 516 contains the type used). The human_readable() function now just outputs 517 decimal kilo/mega/gigabytes (so when du -u says 5.0G it means 5.0 billion 518 bytes). The build infrastructure now notices duplicate commands (so if you 519 cp toys/pending/command.c toys/other/command.c and forget to delete the 520 first one, the build break is now more informative).</p> 521 522 <hr><b>April 20, 2014</b> 523 <blockquote><p>And to this end they built themselves a stupendous supercomputer 524 which was so amazingly intelligent that even before the data banks 525 had been connected up it had started from "I think therefore I am" and got as 526 far as the existence of rice pudding and income tax before anyone managed to 527 turn it off. - The Hitchhiker's Guide to the Galaxy.</p></blockquote> 528 529 <p><a href=downloads/toybox-0.4.8.tar.bz2>Toybox 0.4.8</a> is based on 530 <a href=http://landley.net/hg/toybox/shortlog/1262>commit 1262</a>. And 531 about time too.</p> 532 533 <p>The big news is that the build no longer needs python to generate help.h, 534 that's now done in C. The help text generation is also collating help text 535 from multiple options, merging command line option blocks and usage: lines. 536 There's even a new <a href=help.html>help web page</a>.</p> 537 538 <p><b>New commands:</b> Ifconfig, cpio, and su were cleaned up the rest of the 539 way and promoted out of pending. That saga is mostly explained on the 540 <a href=cleanup.html>cleanup page</a>. Vivek Bhagat's freeramdisk, 541 Isaac Dunham's fsfreeze, and Felix Janda's iconv are also new.</p> 542 543 <p><b>In pending:</b> 544 Ashwini Sharma's team submitted tcpsvd, udpsvd, telnet, telnetd, last, more, 545 groupdel/delgroup, arping, brctl, ftpget, ftpput, printf, reset, and added 546 ipv6 support to traceroute. Kyungwan Han's team submitted modprobe and getty. 547 Vivek Bhagat submitted openvt and deacllocvt. Samuel Holland submitted fold. 548 I wrote a new inflate (zip/zlib/gzip decompression) implementation in 549 compress.c, and still need to do a corresponding deflate (compression-side) 550 and plug them into gzip and zip and so on. (Right now it does zcat.)</p> 551 552 <p>Several commands (vmstat, login, du, vconfig, mountpoint, free, chroot, 553 cut, touch, modinfo, expand) predate the "pending" directory, and are thus 554 in other directories but still need cleanup. Of these, vmstat got some 555 work this time (which would be much easier other vmstat implementations 556 documented what their output actually meant).</p> 557 558 <p><b>Upgrades:</b> Ifconfig grew /prefix netmask support (ala 1.2.3.4/24). Grep now has -zZ to 559 handle null terminated data, cksum grew -H for hex output. Upgraded od so the 560 fields align better when producing multiple output types. Help has -a and -h 561 options (all commands, html output). 562 Bugfix to blkid building for a 32 bit target. The date command can actually 563 set dates now. The O_NOFOLLOW compile time probe didn't work with cross 564 compiling, so it's back to an #ifdef test in portability.h. Nathan McSween 565 sent in a bugfix to od and a portability fix in the common library code. 566 Ashwini Sharma spotted a bug in pidof -o, and added verbose (-v) options 567 to mkdir and ln, and suggested killall should have an -s option and 568 allow -l to take zero arguments. Ashwini Sharma and Felix Janda upgraded 569 tftpd. Fixed dumpleases still using toynet.h after 570 that was removed. Corrected killall return code and error reporting. 571 Isacc Dunham fixed bugs all over the tree, did cleanup on a bunch of 572 pending commands (getty, ftpget, init, openvt, modprobe...), and clarified 573 find's help text. Tom Sparrow ran three different static analyzers on 574 the code, which resulted in a few cleanups. The peek()/poke() functions 575 now use "volatile" to prevent broken compiler "optimizations" to do with 576 aliasing.</p> 577 578 <p><b>Build stuff:</b> Each FOR_xxxx macro now has a complementary CLEANUP_xxxx macro, so you 579 can put multiple commands with different command line options in the same 580 .c file, so they can share infrastructure outside of lib. (This let the 581 bunzip logic move out of lib into bzcat.c.) See XXX for example. 582 i 583 <p>The headers #included in toys.h are now grouped by standard, and headers 584 not listed in Posix or LSB were moved to portability.h. The old xregcomp.h 585 was folded into lib.h because it's posix (and supporting oddball uClibc 586 configurations isn't as important as it once was).</p> 587 588 <p>Regression tested against Ubuntu 8.04 to fix up bit-rot in defconfig 589 build on older systems. (We depend on Posix-2008, but not necessarily 590 the absolute latest build environment.)</p> 591 592 <p><b>In lib</b>: lib/xwrap.c added xgetpwnam(), xchroot(), and lib/lib.c now has names_to_pid(). 593 xsetuid() was replaced with xsetuser() which takes a struct passwd 594 and sets both gid and uid, mkpathat() got factored out into a library command, 595 get_int_value() became atolx_range(), and 596 xmsprintf() is now just xmprintf(). The bunzip2 logic moved from lib into 597 bzcat.c.</p> 598 599 <p><b>Documentation</b>: new <a href=help.html>help page</a> with the 600 help text for all the defconfig commands, using the new help -ah output. 601 The <a href=code.html>source code walkthrough</a> now says more about 602 #including header files, and how the generated/* directory works. The 603 <a href=design.html>design page</a> has some new paragraphs about trading 604 of different kinds of simplicity, and why comments aren't a substitute for 605 good code.

Isaac Dunham sent in cpio.</p> 624 625 <p>Bugfixes: Jeroen van Rijn added a user count to uptime. Elie De Brauwer 626 added -e to watch, removed a memory leak, and fixed a terminal size problem. 627 William Haddon made xargs call its command line once even with blank input 628 (the standard is vague, but builds expect it), and fixed an off by one bug 629 where grep didn't malloc enough space with -E (leading to a segfault). 630 I fixed a glitch in bunzip2 (same one as went into busybox since they're using 631 the code I wrote), in od to fix -t co, -J, and -c options. Add uname -o as a 632 synonym for -s. Build fix to never use $CC without prefixing it with 633 $CROSS_COMPILE (since $HOSTCC could be different). Anca Emanuel spotted 634 a typo in the web page.</p> 635 636 <p>The compile-time command line option parsing got rewritten (ported from 637 bash to C), which should speed up builds a bit and allow code controlled by 638 --longopts to drop out properly when disabled in the configuration. Terminal 639 querying got refactored. Patch's -x option is now more informative (a 640 debug thing if you're trying to figure out why a patch didn't apply). 641 The "toynet.h" file got folded into toys.h since musl supports it and 642 micromanging uClibc options isn't very interesting anymore.

The [-abc] exclude 718 logic should now clear arguments slots when disabling options. Bare --longopts 719 should work now and be able to report errors using their name, the new ; 720 option allows optional arguments to longopts only suppliable with = (I.E. 721 --color and --color=auto but not --color auto).</p> 722 723 <p>I'm gradually weaning the code off of itoa()/utoa() because sprintf 724 does this already. In this case "simple" probably means "let libc do it 725 for us".</p> 726 727 <p>Rewrote for_each_pid_with_name_in() and renamed it to just names_to_pid(). 728 It shouldn't get confused trying to compare absolute and relative paths quite 729 so much anymore.</p> 730 731 <p>lib/llist.c grew a new dlist_pop() function for removing a doubly 732 linked list entry while maintaining a circular list; tail and patch are 733 using it now.</p> 734 735 <p>The musl guys suggested a new optimization flag 736 (-fno-asynchronous-unwind-tables) 737 that shaves about 10% off the binary size by removing a C++ism that crept 738 into gcc's idea of C. While I don't normally try to micromanage the compiler, 739 "-fstop-being-stupid" is a thing you have to hit gcc with from time to time.</p> 740 741 <h3>Bugfixes</h3> 742 743 <p>Felix Janda and I did a largeish rewrite of tail to 744 finally make it work right (we think). Still need to implement tail -f 745 someday (the tricky bit is making -f follow multiple files at once). 746 Felix also reported a bug in xpidfile.</p> 747 748 <p>Juhani Haverinen pointed out that 749 python 3 doesn't work with config2help.py, so the detection logic looks 750 for python2 (until I get around to rewriting that in C). Elie De Brauwer 751 then fixed our first attempt at this, and also fixed uname's help string.</p> 752 753 <p>Ashwini Sharma 754 pointed out the build was making a FLAG_ macro for " " which broke some 755 configurations. (That's a control character, not a command line option.)</p> 756 757 <p>Jacek Bukarewicz pointed out a bug in chdir permission handling, and 758 a way to make env segfault. Both should be fixed now.</p> 759 760 <p>The new function xexec_optargs() 761 replaces calls to xexec(toys.optargs) to avoid freeing and reusing optargs 762 during option parsing screwing stuff up (such as netcat's exec mode).</p> 763 764 <p>The stat command's %a output was padded with leading zeroes, which 765 didn't match anybody else's behavior and thus made the test suite hiccup 766 between TEST_HOST and testing toybox.

It adds 788 uuencode and uudecode from Erich Plondke, and enables Luis Morales' "who" by 789 default. Felix Janda and I cleaned up last year's "stat" submission and 790 enabled it. Ivo van Poorten added "groups". 791 Andre Renaud added "lsusb". I implemented "split", "pivot_root", and "mv". 792 </p> 793 794 <p>The "help" command is implemented differently now (lib/help.c) and 795 each command can now understand --help (including both "toybox --help" 796 and "toybox --help command" in the multiplexer).</p> 797 798 <p>The "pending" directory has several commands (find, xzcat, nbd-client, 799 logger, expr) which work but are not enabled by default pending further cleanup. 800 Ifconfig is enabled, but still in pending because it's only 2/3 cleaned up. 801 (It's an awkward halfway state but I'm not holding up the release for it.)</p> 802 803 <p>I'm <a href=cleanup.html>documenting the cleanups</a> to teach 804 more people to do it, but the writeups aren't caught up yet. The 805 <a href=roadmap.html>roadmap</a> also got updated a bit with further analysis 806 of other projects, and the README and about pages got updated.</p> 807 808 <p>Fixed _another_ "ls -C" segfault when terminal size can't be detected, 809 condensed the ls help text to fit on one page, implented --color, and taught 810 -l to print the major, minor numbers when showing block/char devices. 811 Argument parsing now handles "--" properly (to end option checking), 812 and the infrastructure can now handle bare --longopts that have no 813 corresponding short option (both were implemented before but didn't work). 814 Fixed an old bug in "patch", chmod grew -f, who grew -a. Isaac Dunham 815 fixed "-" vs "_" handling in modinfo, added a "firmware" output 816 field, added -b and -k support, and taught it that the ".ko" extension means 817 to look for the file at the specified path instead of under /lib. Felix Janda 818 moved file permission display code to lib so ls and 819 stat could share it. Ashwini Sharma spotted a bug in xabspath when the 820 last path component exists but we haven't got permissions to open it 821 (ala readlink -f /dev/sda as a normal user). 822 </p> 823 824 <p>In the build infrastructure, scripts/findglobals.sh finds leaked global 825 variables. (Leaked means they aren't part of the global union: Other than glibc 826 debris, toybox should define "this", "toy_list", "toybuf", and "toys", and 827 that's it; the rest add memory footprint to every command for the benefit of 828 just one command; use GLOBALS() to stick 'em in the union.) Static linking 829 against libraries other than the host's libc now applies to feature probes 830 for unshare and such. Neuter stupid internationalization support that makes 831 various host "sort" commands put things in an order other than alphabetical 832 (breaking the multiplexer's binary search on command names). 833 834 <p>You should now be able to build from a source control snapshot on a build 835 system that hasn't got python: if you disable CONFIG_TOYBOX_HELP. (The 836 release tarballs ship generated/help.h, but it's not in source control. 837 Eventually I should rewrite that python script in C.)</p> 838 </p> 839 840 <p><b>LICENSE TWEAK</b>: After <a href=http://lists.landley.net/pipermail/toybox-landley.net/2013-March/000794.html>discussion</a> on the mailing list the "2 clause 841 BSD" <a href=license.html>license</a> got slightly simplified so the first 842 paragraph now says:</p> 843 844 <blockquote><p>Permission to use, copy, modify, and/or distribute this 845 software for any purpose with or without fee is hereby granted.</p></blockquote> 846 847 <p>It used to continue "provided that the above copyright notice and this 848 permission notice appear in all copies", but A) what's the point?

There 922 are now exactly 100 commands in defconfig (of a little over 220 on the 923 <a href=roadmap.html>todo list</a>).</p> 924 925 <p>Elie De Brauwer added the rev command, cleaned up tac, implemented the -s 926 and -f flags for seq, added -v and -i to killall (and fixed killall not to 927 kill itself before finishing its pid list), and added to the test suite. 928 Felix Janda added -m to mkdir, pwd -L and -P, and more test suite entries.</p> 929 930 <p>Rob Landley added the losetup command, and fixed the existing ls, cp, and 931 readlink commands. The segfault in ls 932 happened when it couldn't determine the screen size (last release changed the 933 default to -C and a screen size of 0 made column view unhappy), and cp got an 934 extensive rewrite bringing it up to date with the dirtree changes and fixing 935 a number of things it never did right in the first place. The xabspath() 936 code in the library now handles a symlink after ".." properly (and the test 937 suite checks for it).</p> 938 939 <p>Infrastructure-wise the code is better about automatically setting the 940 error return code properly. Now error_msg() sets the exit code to 1 if it's 941 still defaulting to 0, and the global exit path does a fflush(NULL) with error 942 bit check rather than trying to be quite so granular about flushing. (That 943 means if we use printf() instead of xprintf() it still exits with the right 944 error code, it just doesn't end the program early on an output error.) 945 Minor bugfix so TOYBOX_DEBUG 946 doesn't always warn about the lack of suid bit when toybox is built with 947 at least one STAYROOT command. Bugfix for the option [grouping] logic 948 (and then further fixes to the error reporting pointed out by Ashwini Sharma). 949 dirtree_handle_callback() now has a prefix like the rest of the dirtree 950 functions. A lot of stuff doing manual path handling was switched to using 951 libc basename() (including, embarassingly, the basename command), which means 952 it now correctly detects "/trailing/slash/" which the previous code didn't.</p> 953 954 <p>Also, last release included some accidentally checked in debug code that 955 disabled compiler optimization, so the binary size bloated a bit.

Linux 3.7 came out, meaning it's time to do an Aboriginal 967 Linux release, and that should use a stable version of toybox. So here's 968 a new stable version.</p> 969 970 <p>The new commands are cut (from Jason Kyungwan Han), touch 971 (from Choubey Ji), expand (from Jonathan Clairembault, and he fixed a 972 bug in login), and rm (from Rob Landley). Felix Janda added UTF-8 973 support infrastructure (for non-ascii character sets) with a config option. 974 Elie De Brauwer added tests for cat and sha1sum, and -so options to pidof. 975 The "ls" command defaults to -C (column view) now, and "readlink" now supports 976 -fenq.</p> 977 978 <p>Portability work: toybox should now build against the musl C library, 979 and against older glibc versions (circa 2008, much before that and kernel 980 features we depend on start to drop out).</p> 981 982 <p>The whole codebase got reindented from "one tab" to "two spaces" per 983 level. The option parsing logic now understands [groups] of commands (when more 984 than one in a group is selected it can switch the others off, or error out, 985 or other things). The error_exit() infrastructure can now longjmp back to an 986 earlier point instead of exiting. Each toys/* directory now has a README, 987 the first line of which is the fancy name menuconfig uses for the directory 988 (so no more hardwired directory list in scripts/genconfig.sh).</p> 989 990 <p>Fixed a filehandle leak in getmountlist(). 991 Pass parent pointer to dirtree_add_node() so it can give error messages with 992 full path. The yesno() function now always reads from stdin and writes to 993 stderr (we can retry tty checking complexity once we've got commands needing 994 it).</p> 995 996 <p>The open group broke their website so the 997 <a href=http://opengroup.org/onlinepubs/9699919799>old links</a> to POSIX 2008 998 now <a href=http://pubs.opengroup.org/onlinepubs/9699919799>need to start with 999 pubs</a>.

I can add a config option 1005 to do it Posix's way, which is more brittle and needs extra security checks, 1006 but am waiting for somebody to complain first.

The df command follows symlinks to get the actual device name. 1023 Felix Janda added -m support to wc (for utf8).</p> 1024 1025 <p>On the infrastructure side, the commands have now been grouped into 1026 "posix", "lsb", and "other" subdirectories (for things required by Posix-2008, 1027 the Linux Standard Base 4.1, and commands in neither). This affects menuconfig 1028 and the actual source layout (toys/cp.c is now toys/posix/cp.c, and so on). 1029 An android directory is planned (see the updated 1030 <a href=roadmap.html#android>android roadmap analysis</a>).</p> 1031 1032 <p>The FLAG_ macros for command option parsing and TT alias for the command's 1033 global block are now automatically generated, commands should 1034 #define FOR_commandname before #including <toys.h> to get the macros for that 1035 command.</p> 1036 1037 <p>An upgrade to the build infrastructure now allows commands with _ and - 1038 in them, such as switch_root.</p> 1039 1040 <p>Bugfixes: Avery Pennarun spotted a case where ls showed uid twice instead of 1041 uid and gid, and that nice was using the wrong range of numbers. 1042 The ls command also recursed inappropriately last time (not quite 1043 properly converted for the dirtree changes last release), and now it's 1044 fixed. Roy Tam pointed out a glitch in sh, and fixed df's percentage 1045 calculation to match the POSIX spec. The kernel build didn't like our mktemp 1046 and it does now. The wc command wasn't quite posix compliant (trailing spaces 1047 break stuff). The ls command recursed inappropriately last time (not quite 1048 properly converted for the dirtree changes last release), and now it's 1049 fixed. The catv command wasn't displaying byte 255 correctly. Some lib 1050 fixes (thinko in xpidfile). Fixed uname -m when running a 32 bit x86 binary 1051 on an x86-64 host (it lies and says the system is i686, i586, or i486 depending 1052 on what the toolchain that built the binary supported. This makes builds in 1053 a 32 bit chroot on a 64 bit kernel break less.) The df command was checking 1054 partitions in the wrong order (displaying undermounts instead of overmounts: 1055 this used to work but some library code changed out from under it and it 1056 wasn't updated to match until now). Felix Janda filled out the test suite 1057 some more. The patch file creation logic got tweaked several times to 1058 successfully apply more patches.
